I felt misled at first feeling I needed to purchase the pdf filler after I had already used it. The customer support team replied quickly and resolved my issue.

Love the product
Love the product. Works fantastic for me as a property manager. I am using this tool for not only real estate purchase forms but also tenant forms! Especially useful in our mobile workforce where people are not available to sign documents or not even in the same state. Highly recommend PDFfiller!

Great Product!
There are many companies that can only access documents in .pdf format so we can edit the documents and send them efficiently using PDFfiller.
It takes a while to learn to edit documents properly.

Adobe for Life
Overall, it's an amazing feature of the Adobe family that comes in handy for myself and especially in my industry where contracts are signed and requested frequently.
So you're working on a project, job, whatever and you get a form that needs to be filled out, signed, and returned. It's a PDF file which is great because nothing can be edited off the original form. You're only responsibility is to fill it out and send it back, but you don't have a printer available, there's no fax machine around, and this form needs to be completed ASAP. The PDF filler is an amazing tool that gets the job done. Not only does it allow you to fill in information on any PDF file, it also allows you to upload your signature to docs as well.
So while you can add your information to any pdf file, some of the files don't always allow for ease of filling out. For example, some forms allow you to type into blank spaces where words and information are supposed to go, while others have distortion issues and don't always allow for certain spaces to be typed into.

One of the best PDF filler's on the market. Various ways to collect your initials and signatures, easy to use and well worth it... Think a bit pricey, but for what it offers it is highly recommended.
SUGGESTION: Add a once off option - I only use it occasionally.

Just a few suggestions
I have used some other comparable products, but pdfFiller offers the online hosting that makes it super convenient for the user to fill out the form without having to download the form first. However, I have a couple of suggestions. I wish the pdfFiller could have the feature to automatically convert the raw entry data (e.g. phone number 1234567890) into the selected format (e.g. (123) 456-7890), instead of asking the user to enter it into the specific format. I also noticed the accident that some fields will be deleted accidentally when saving the edited version in LinkToFill. It happened several times to me when I was editing my file. Not sure if that's an internal bug or an accident from the internet interruption.

Perfect for merging multiple JPG images into a compact PDF
This app / web page allowed me to easily merge six JPG image files (each 2550x3300 pixels, some included photos) into a single compressed PDF document that was small enough (7MB) to be easily shared as an email attachment. Did exactly the job I wanted it to!
